UNITED s'r'rs EMIL REICHEN'BAUM,

This invention relates'to a power driven filing attachment for .a drill press, and'the' object is to provide in connection with a suitable frame work, provlded with guldes, a vertically reciprocatlng frame in WlllCh the 'file is mounted, and means for imparting movement to the frame.

. A further objectis to provide, in connection with the construction above specified, means for varying the strokes of the file holding device or frame.

A still further object is to provide a table for holding the work being operated upon, and means for varying the angle of the table with reference to the file.

With the foregoing and other objects in view. the invention consistsin the novel construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings:

Figure 1 is a view of the machine in side elevation.

Figure 2 is a view in rear elevation.

Figure 3 is a horizontal section, on the line 33 of Figure 1. r

Figure 4 is a perspective View 'of the file holding frame. 1 i

The main frame includes a base 10, an upright portion 12, and a head 14 provided with bearings 15 'and' 16 for mounting the horizontal shaft 17 V The head is provided with a bearing 18 mounting a short vertical shaft 20'having a tapered portion 21, this shaft carrying on the lower end thereof a beveled gear wheel 22.

Power is applied through the shaft 20, and thence to the bevel gear wheel or pinion 22 meshing with a beveled pinion 23 on shaft 17 rotary movement being imparted to said shaft last named and to the disk 25, which in turn imparts movement to the element referred to below.

The disk is provided with a transverse or FLINT, M CHI AN. f

adjustment radially of the block 27 which f has dovetail connection withthe walls of the groove. The pitman 28 connected with the block just referred to is also pivotally connected with a stud 29 projecting from the frame 30 operating in guides -31 on the vertical element of the frame of the machine. r

The frame 30 includes vertical elements 31 and the laterally extending arms 32 .and33,

each being provided with'a socket portion- 34 for receiving one end, of the file 35..

Thumb screws 36 serve to retainfthe'file' in the socket members. In view of the adjustable mounting of the .block'25 with reference to the disk 25, the length of the stroke,

of the frame or file holding device 30 may be varied as desired. 1

A table 37 is adjustably mounted on an upright 38 secured to the base 10, in the manner illustrated. The adjustable connection is effectedby. means of the screw 40 passing through cars 41 on the table 37, and

vertical element ofthestand.

The various adjustments permit ofthe engagement of thework by the tojol'in the manner desired for producing a given result,

and also permit of the use of a considerable portion of the file;

That is claimed is: V 7 v In a" device of the class described, a main frame, provided with guideways, a file hold-v ing frame movable in the guideway's, a shaft and meansifor driving the latter and means for imparting movement to the second named frame; from said shaft, the file hold- 90 ing frame comprising a plate memberthe edge portions of which engage the guide.

ways. spaced laterally extending arms carried by the plate and each provided with a socket portion for receiving the op posite ends of a file, devices forclamping the file in the sockets, a stud projecting from the plate in a direction opposite to that in which the arms extend and having connection with said means for imparting movement.
